1+ Check or replace your clutch switch.

If in neutral when you just crack the throttle 1-2% and hold it steady will it act up?
if not i bet it is your clutch switch.

New developments

The TPS voltage was set 0,8v at idle and 4,0... something at full throttle.

Set it to 0,57v cold. But when opening the throttle it'll go to 3,98v... shouldn't it be 3,60/3,70 volts?

When was about to start the bike, the battery was weak.. today, battery fully charged, checked the TPS, was unchanged, started the bike... idle at 4500rpms...

I'm thinking that the battery may be toast.

when adjusting the TPS is is necessary the 15 minute procedure?

Idle holding at 4000rpm

TPS adjusted, then loosing adjustments. So I am checking it dismounted:
Resistance between black and yellow wires:1,35 Ohm
turning a screwdriver leftwards inside the TPS hole, maybe 5 degrees goes to 1.93 Ohm and then to infinity.
I wonder what are the correct numbers.
Anybody?

That sounds like a bad spot in the sensor. Mine did the exact same thing. The sensor for an 11 is plug and play. I think the new ones have finer increments for TPS voltage because mine runs so much better than it ever did!

Dunno.

I've ran away from that issue after spending too much time banging my head on the bike... replaced the whole unit. Fixed in no time.

Learned alot at that time... mostly to keeps hands off!

Gefr,
Here is a measurement of a new 990 ADV LC8 (ktm p/n 61041077000), there are two but they are electrically the same.
blu wire +4.984 from supply
blk wire is ground ref.
Yellow is signal out (wiper of pot)
nominal sensor is 0 to 5,000. ohms
Note, the main point is not the slope or if it is a straight line, but that the voltage out signal goes from 0 to the supply rail without any dropouts or spikes, and moves from 0 to rail voltage (your supply voltage) with full range and repeatable.
Cheers... defaultgateway

Well heres my update.

I took Gustos advice and purchased a s/h throttle body assembly off ebay, but I had already narrowed my problem down to the TB wiring harness. So I really bought the TBs to get the wiring harness and have a back up.
I used the original TBs including all the ancillaries except for the wiring, I really wanted to prove to myself that the problem was in the harness.
I have just done two rides totaling 2600km and the bike ran perfectly. I havent stripped the old harness yet but I could tell with a multimeter that there was a potential fault in there.

My 4000 rpm idle is gone

So you conclude it was harness problem?

Can we say the erratic idle and all EFI gremlins are problems caused from bad TPS?
Seems the error code does not show up always.

Absolutely NOT

As I said I am using all my original old parts including TPS and my problems have been fixed. The only part that fixed the eractic idle was the wiring loom.


I would love to say that I found the problem in the loom but I cant, I stripped it back to the join that combines the common injector wires which gave a bad resistance reading but it doesnt look bad and although I can fiddle with the wires and change the reading it is not conclusive.

Having a faulty TPS I fiddled with it and here are the results:

At TPS voltage 0.72V idle was diving to a stall while at 0.61V idle is sticking at 2000rpm and finally resting at 1500rpm after a while. At the adjusting bolt, moving the sensor upwards (turning the sensor anticlockwise) increases TPS voltage and lowers idle rpm, moving the sensor downwards (clockwise) TPS voltage gets lower and idle settles higher.
When TPS is damaged, the sweet spot is damaged so it cannot settle to the correct idle.

Not yet.

I managed to have it adjusted so I do not get sudden engine death or idle hanging at 4000rpm. My idle often stays at 2000rpm and then settles to the normal 1450rpm. I will replace ASAP with a used one in good condition.
Cheers.

I had similar symptoms and tried TPS settings with no luck. Finally changed the idle motor and bike works normal.

Gefr, did you ever sort this out?
